Imperial Berkey® 4.5 Gallon Gravity-Fed Water Filtration System.

High-Capacity Water Filtration for Daily Use
The Imperial Berkey® System is a gravity-fed water filtration system designed for households, small offices, or groups of 4–6 people. With a large 4.5-gallon capacity, it’s ideal for situations where higher water volume is needed throughout the day. The stainless steel construction offers a sleek, durable design that works well in kitchens, breakrooms, or shared spaces.

Efficient and Economical
The system comes equipped with two Black Berkey® Filtration Elements, designed to reduce a wide range of unwanted substances commonly found in treated tap water — including certain heavy metals, chlorine, VOCs, and other contaminants. Each set of filters can handle up to 6,000 gallons before replacement, delivering clean, better-tasting water at an average cost of less than 2 cents per gallon.

Expandable and Customizable
For increased filtration speed, the system can be expanded to accommodate up to 4 Black Berkey® Elements (sold separately). Optional Berkey® PF-2™ Fluoride and Arsenic Reduction Elements can also be added for additional filtration needs.

Trusted Berkey Performance
Backed by independent laboratory testing, the imperial Berkey combines capacity, efficiency and convenience in one powerful filtration solution.
